INTAGLIO (an Ital. word, from intagliare, to incise, cut into), a form of engraving or carving, in which the pattern or design is sunk below the surface of the material thus treated, opposed to " cameo " or " relievo " carving or engraving where the design is raised. Intaglio is thus applied to incised gems, as cameo (q.v.) to gems cut in relief (see GEMS).
